Yes it's normally slack. You use the inner limit screw to determine the position for the smallest chainring, and the cable should be slack enough to allow it the FD to rest against the limit.
On a triple, the cable tension is set based on middle ring, while ensuring that it also shifts effectively to the larger. On a double the tension is set based on smooth shifting to the outer ring.
The systems are designed with slightly excess travel for each click, so the cable be slack on the inner, and slightly stretched while on the outer, where the outer limit is used to fine tune the position against what would be a slight overshift.
